Pest and Disease Management

In a natural ecosystem, plants are continuously being attacked by all kinds of pests and pathogens such as insects, fungi and bacteria. In the natural ecosystem plants can survive thanks to the help of natural enemies of these unwanted pests and pathogens. In this way, population developments of all players in a natural ecosystem are controlled. But compared to nature, cropping systems are less stable due to human interferences.

Biological control or biocontrol is a method of controlling pests such as insects , mites , weeds and plant diseases using other organisms. It can be an important component of integrated pest management IPM programs. There are three basic strategies for biological pest control: classical importation , where a natural enemy of a pest is introduced in the hope of achieving control; inductive augmentation , in which a large population of natural enemies are administered for quick pest control; and inoculative conservation , in which measures are taken to maintain natural enemies through regular reestablishment.

Different approaches may be used to prevent, mitigate or control plant diseases. Beyond good agronomic and horticultural practices, growers often rely heavily on chemical fertilizers and pesticides. Such inputs to agriculture have contributed significantly to the spectacular improvements in crop productivity and quality over the past years. Today, there are strict regulations on chemical pesticide use, and there is political pressure to remove the most hazardous chemicals from the market. Additionally, the spread of plant diseases in natural ecosystems may preclude successful application of chemicals, because of the scale to which such applications might have to be applied.
